OwnCloud is an open-source alternative to 'cloud' storage things like dropbox, as well as web-app things like calendars and addressbooks, and even Google Docs. It's probably best to go with the completely free alternative called NextCloud, but that's not availible on my NAS :|

Using caldav on Android things sync just fine with the link provided in ownCloud. But with Lightning you need to go through all the different calendars and get individual links. A bit of a pain!

Having trouble importing contacts from one ownCloud to NextCloud. This guy seems to have a solution down the bottom of this thread, just renaming some things: https://github.com/nextcloud/contacts/issues/433

QNAP NASes don't seem to like installing add-ons through ownCloud >:| The probablem being that the version is stuck on 8-something, whereas the current OwnCloud version is 10-something! Both the deleted methods below didn't actually work.

Options are:

• Use old versions of the add-ons found here: owncloudarchive (insecure)
• Use 3rd-party repo qnapclub (https://www.qnapclub.eu/en/repo.xml), which had up-to-date versions of NextCloud and ownCloud. Not sure how to get SSL set-up for them yet. Nor can I find the NextCloud directory after it installed, even thoug hit works. ＭＹＳＴＥＲＩＯＵＳ.

So you have to manually download them and place them in the apps directory, or make a secondary directory if you want to keep them seperate ().

But if you add these lines to your config.php it should be fixed. ※ the appstoreurl is different than in the one in config.php.sample. <code> 'appstoreenabled' ⇒ true, 'appstoreurl' ⇒ 'https://marketplace.owncloud.com/api/v0', </code>

The trouble-free-est way to upgrade seems to be to ssh into the server, then run php occ upgrade from the directory owncloud's installed to.

To upgrade to a new version (IE 9 > 10) you have to download and reinstall first, retaining the data and config directories. My process is:

• wget [latest version] to download latest version.
• mv [owncloud dir] [owncloud dir]-backup to rename.
• tar xvjf [latest version archive] to extract archive.
• cp -avr [owncloud dir]-backup/config [owncloud dir]/config
cp -avr [owncloud dir]-backup/data [owncloud dir]/data to copy over data and configuation stuffs.
• cd [owncloud dir] and php occ upgrade

• NextCloud
